Scriptrunner listener doesn't work

[Volodymyr]

Hi there,

How does the script work?
The listener checks if the issue has an Epic and if so, checks all the issues in it. Sums the time for field "Original Estimate" from all issues and sets the sum in the Epic's field.

I have a script that I finished 2 days ago and tested it on all scenarios. The script worked as it should in each test and stopped working the next day, namely, everything is the same as before in the logs, but the specified time does not appear in the epic. The field is on the screen, everything is in order with the permissions. Nothing has changed in this regard.

You can see from the logs that the value appears in the epic, but if you immediately check it through the Scriptrunner console, then the epic has a value of 0.

Maybe someone has thoughts about what I did wrong.
If you have any thoughts on how to improve the script, please let me know.
Thank you.

Edit: The listener works for 3 events (issue created, updated, deleted)

I found the answer.
I thought "setEstimate()" method was only responsible for "Remaining Estimate", but it turns out it also clears "Original Estimate".
As soon as I commented out this line, it started working as before.

Those are examples of logs

and when I immediately check the result in the console, I see this:
